Black dot from scalp are back. They started after my kitten

Customer Question

Black dot from scalp are back. They started after my kitten kneaded on my scalp in 2010. My immune system is low from late-disseminated Lyme Disease-which was treated for 6 mo. on IV antibiotics. The scaling and specs only lessened. I just got pelvic surgery and my sq immnoglobulin I was cut off from-insurance not paying pharmacy. They seemed to go away while on cipro. Now they are back with a vengeance! Help! Can't I 'make' a Dr. take a sample? NO ONE will take biological sample! I am a fish and wildlife Technician: WHY is this such a big deal to Doctors? Send the sample to a LAB for analysis right?!
